Quickstart: first task in 2 minutes

  1. Install into your client (tabs below). One JSON block, or one click in Cursor or VS Code.
  2. Restart your client. You should see Reflex's tools listed.
  3. Sign in once: ask your agent to run reflex_auth with action: "login". It opens your browser, authenticates you, and saves a key locally — no manual copying. Already signed up on the site? You can paste your key from the welcome screen instead.
  4. Ask: "Open news.ycombinator.com and tell me the top 3 stories." Your agent will call reflex_open once and answer. That's 1 credit.
  5. Try something with steps: "Log into my staging app and check the orders page for anything red." A typical multi-step task is 2-3 credits.

Install into your client

Fastest: the one-click desktop extension. Download the bundle, double-click, and paste your API key when prompted. It ships its own runtime, so you do not need Node installed.

Or paste this into your config manually (needs Node 18+):

json
{
  "mcpServers": {
    "reflex": {
      "command": "npx",
      "args": [
        "-y",
        "reflex-browser@latest",
        "mcp"
      ]
    }
  }
}

Config path: macOS ~/Library/Application Support/Claude/claude_desktop_config.json, Windows %APPDATA%\Claude\claude_desktop_config.json. Restart Claude Desktop fully (quit from the menu bar, not just close the window).

Platform: macOS supported today; Windows is beta (see troubleshooting). After install, run reflex_auth with action: "login" to sign in — or paste a key from your welcome screen.
